Hello,
I wouldn't consider myself a network engineer, nor do I have any formal training, but why don't ISPs peer with every other ISP? It would only save EVERYONE money if they did this, no? Only issue I see is with possibly hijacked / malicious AS owners, but that's not very common to do without being caught.
The answer to _every_ question that starts of "why don't they..." is "money". Who pays for the circuits to establish a 'peering connection' with an ISP half-the world away? How much does traffic does "Joes Bait Shop and ISP" in Painted Privvy, Nebraska have with a community ISP in Honshu, JP?"
